Application filed February 36. 1918. Serial No. 217,662h' To all whom it may concern-w.

Be it known that T, Pn'rnn linen l thiu- DELL, a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Troon, Ayrshire, Scotland, have invented a certain new and useful Improvement in Apparatus for Hashing Photographic Prints or the like, of which the tollowing is a specification.

This invention relates to a device whereby photographic prints or other products may be washed free from hypo or other chemicals.

To receive the prints or the like there is employed a preferably oval basin or container for water in which theprints or the like may be immersed.

.The primary ob 'ect of the invention to provide for rapid circulation of the water in the basin, with which object in view there are'provided water conduits terminating in nozzles which deliver water intermittently in jets to the basin; said conduits being controlled by a multiple-way tap, say a four-way tap, the key elementfoi' which is rotated intermittently; or, in lieu of a fourway tap, there'may be employed say a twoway tap with a continuously openby-pass in substitution for two of the ways or the iour-way tap in the accompanying drawings Figures 1 and are elevations partly in section at right an piles to one another, Fig. 3 is apart sectional plan and Fig. t a sectional detail view showing one embodiment of the invention.

Referring to Figs. 1. to 4%, 1 denotes a supply pipe to which water is conducted irom any suitable source.

denotes a branch from said supply pipe id branch 2 servin tolead water, (under ontrol of a stop cock 3), into a tank 4: superimposed. on the basin 5, said tank a being fitted with a siphon 6 adapted to discharge the water in the tank at when the wator reaches a predetermined level in the tank. The speed with which the tank 4: fills depends on the rate of flow of water through the branch 2. V

Sustained within said tank 4 is a ball float T which, when the siphonic discharge is effected, falls to the bottom of the tank 4. Projecting upwardly from the float 7 is a tube 8 of small diameter telescopically movable on the guide rod 9 held rigidly by a bracket 10 fixed to the top of the tank 4.

' ll denotes the revoluble element or key lar groove 18 in the barrel 12 of the tap whereby water received by the supply pipe 1 is admitted into the interior ot'the key.

.ll k e re isa. c-0111 c or- Fo ne'l in th 1 y 11 n l gatel e toration 19 which in the rotation of the key 11 registerssuccessively with our circular perforations 20 in the barrel 12, through which perforations 20 the water supply is delivered successively into the conduit pi es 13, i l, 15, 16. r

Fitted to the key 11 are tour arms or spokes 21 disposed at right angles to one another and adapted successively to obstruct the path'oi a trigger or striker 22 hingedly connected to the tube 8 and adapted to be guided, for example by two rigid rods 23 parallel to the tube 8. As will be understood, when the float 7 rises, the trigger 22 engages one oi"? the tour arms or spokes 21 n. d propels such rm and therewith the key 11 through a quarter of a revolution. The trigger 22 then. remains under such spoke or arm. l/Vhen the tank 4: is discharged, the float 7 and therewith the tube 8 and trigger 22 descend. The trigger being hinged, is rigid in pushing upwardly against the'arm or spoke propelled thereby, but in. its downward movement it yields and trips over the next arm. The described movement of the float is repeated four times for every complete revolution of the key 11..

The conduit pipes 13,14, 15 and 16 deliver rater to the basin as follows.

The conduit pip 13 from the first Way of the tap is led into a pocket 24 outside the basin 5, and is fitted with two nozzles 25 (for small sizes of apparatus one nozzle may suilice) located say about one inch and three inches, respectively, beneath the water level in the basin, said nozzles 25 being arranged to direct their jets tangentially of the basin. The basin communicates with the pocket by way of perforations in the'side of the basin and the nozzles are so arranged that, without themselves projecting or'protruding, they direct their respective jets directly through individual perforations. In addition to the nozzles 25 an additional nozzle or outlet 25 is provided at a depth of 'iertorated side of the basin while the tangential jets are in operation."

The conduit 14: from the second way ot the tap is provided with twonozzles 26 (or it might be a single nozzle) located about one mob. and three inches, respectively, above the perforated inner bottom of the basin at a noint'angnlarly spaced iroin the nozzle The jets from the nozzles are directed not quite radially but rather eccentrically so as to impinge upon the opposite side of the basin and cause prints, contained in ti basin to be carried ton-aid the point whence they will be driven by the no low from tl opposite tangential The stopped end 0 the pipe 14 and the nozzles 26 are contained within a pocket 28. similar to the pocket and also in communication by way 01" per forations in the side of the basin with the interior of the basin, and the nozzles direct their respective directly through v individual perforations.

The conduit pipe 15 from the third way oi the tap ied to the pocket and pro vided with tangentially directed nozzles facing in the opposite dir ction to the noz zles An additional nozzle 29 directs a jet of. small volume substantially radiall; and'through an indivi l peri'oration.

The con it pipe 1'6 roin the fourth we" of the tap is led to the pocket 28 nd provided with nozzles 30 whicn direct jet-F: converging toward the nozzles 26.

The siphon pipe 6 by way ot' which the contents of the tank 4; are discharged directed toward and 0Y6? the center of the basin and :tnrnisnes in effect an additional jet.

The basin is drainco lroin the botton waste pipe 31 which. is fitted at the hi5; point with a cock 32 and may be arranged to act as a siphon or overflow according as the cock is open or closed. 33 denotes drain tap.

To prevent prints from getting into the ipe 31 the is formed with a double item of which the or member 2-? is perforated and formed with an undulating side of the basin and so close the perform tions therein.

What I claim is 1. in an apparatus for washing photographic prints and the like, in combination, a basin formed with spaced pockets communicating with the interior oi the'basin, a multiple-ways tap, a supply pipe con nected to said tap, unidirectionally rotatable key controlling the Ways of said tap and a plurality of outlet conduits connected to said tap and having differently directed discharge ends within said pockets.

2. in an apparatus for washing photographic prints and the like, in. combination, a basin formed with spaced pockets communicating with the interior of the basin, a n'mltinle-ways tap, a supply pipe connected to said tap, a unidirectionally rotatable key coi' trolling the ways of said tap, a plurality {of outlet conduits connected to said tap and e ends within said pockets,

having discha and a pipe for introducing water substantially centrally over said basin.

3. in an apparatus for washing photo phic prints l the like, in combination, a watei cont basin haying perforations in its side 1 formed with external pockets communicating with the interior of said he in by way of saidjperforations, said basin so shaped as to prevent adhesion of prints or the like to the side thereof, amu]tiple-ways tap, a supply pipe connected to said and conduits also connected to said tap, said conduits haying differently directed discharge ends within said pockets, said conduits serving to lead jets ot water i nittently to said pockets.

4.. in an apparatus for washing photographic prints and the like, in combination,

a basin having perforations in side and foi'ined with external pockets communicating with the interior oi said basin by Way 01''? said perforations, said basin having a double bottom, the inner member of which is perforated and undulated and its sides being formed with. internal ribs, a multipleways tap, a supply pipe connected to said tap, and conduits also connected to said tap. said conduits having diilcrently directed dis barge ends within said pockets, said con duits serving to lead jets of water into-innit" tentiy to said pockets.

In testimony whereof I have signed my name to this specific-a ion in the presence of two subscribing witnesses.
